NOTE:

Throughout this handbook, reference is made to left, front, and rear when describing locations.

These reference locations are to be considered as those viewed from the operator’s seat with the superstructure facing forward over the front of the carrier frame.

This Operator Manual provides important information for the operator of the Model RT765E-2 Grove Crane.

The rough terrain crane incorporates an all welded steel frame, using planetary drive axles to provide four-wheel drive. Axle steering is accomplished utilizing hydraulic steer cylinders. The engine is mounted at the rear of the crane and provides motive power through a six speed forward and reverse transmission. Hydraulic, double box, sliding beam outriggers are integral with the frame.

The carrier frame incorporates an integral fifth wheel, to which the rear axle is mounted, to provide axle oscillation.

Axle oscillation lockout is automatic when the superstructure rotates from the travel position.

The superstructure is capable of 360° rotation in either direction. All crane functions are controlled from the fullyenclosed cab mounted on the superstructure. The crane is equipped with a four-section, full power, sequenced and synchronized boom. Additional reach is obtained by utilizing an optional swingaway boom extension. Lifting is provided by a main hoist and an optional auxiliary hoist.

RT765E-2 OPERATOR’S MANUAL

loads. Manitowoc has been an industry leader in the incorporation of operational aids into the design of its cranes.

Federal law requires that cranes be properly maintained and kept in good working condition. The manuals that Manitowoc provides that are specific for each crane and the manufacturer’s manuals for the operational aids shall be followed. If an operational aid should fail to work properly, the crane user or owner must assure that repair or recalibration is accomplished as soon as is reasonably possible. If immediate repair or recalibration of an operational aid is not possible and there are exceptional circumstances which justify continued short-term use of the crane when operational aids are inoperative or malfunctioning, the following requirements shall apply for continued use or shutdown of the crane: •

•

•

•

Steps shall be taken to schedule repairs and recalibration immediately. The operational aids shall be put back into service as soon as replacement parts, if required, are available and the repairs and recalibration can be carried out. Every reasonable effort must be made to expedite repairs and recalibration.

When a Load Indicator, Rated Capacity Indicator, or Rated Capacity Limiter is inoperative or malfunctioning, the designated person responsible for supervising the lifting operations shall establish procedures for determining load weights and shall ascertain that the weight of the load does not exceed the crane ratings at the radius where the load is to be handled.

When a Boom Angle or Radius Indicator is inoperative or malfunctioning, the radius or boom angle shall be determined by measurement.

When an Anti-Block Device, Two-Blocking Damage Prevention or Two-Block Warning Device is inoperative or malfunctioning, the designated person responsible for supervising the lifting operations shall establish procedures, such as assigning an additional signal person to furnish equivalent protection. This does not apply when lifting personnel in load-line supported personnel platforms. Personnel shall not be lifted when anti-two-block devices are not functioning properly.

•

When a Boom Length Indicator is inoperative or malfunctioning, the designated person responsible for supervising the lifting operations shall establish the boom lengths at which the lift will be made by actual measurements or marking on the boom.

•

When a Level Indicator is inoperative or malfunctioning, other means shall be used to level the crane.

Never interfere with the proper functioning of operational aids or warning devices.

Under no condition should it be relied upon to replace the use of Load Charts and operating instructions. Sole reliance upon these electronic aids in place of good operating practices can cause an accident.

Know the weight of all loads and always check the capacity of the crane as shown on the Load Chart before making any lifts.

NEVER exceed the rated capacity shown on the Load Chart.

Always check the Load Chart to ensure the load to be lifted at the desired radius is within the rated capacity of the crane.

For detailed information concerning the operation and maintenance of the load moment indicating system installed on the crane, see the manufacturer’s manual supplied with the crane.

Anti-Two-Blocking Device This crane should have a functional Anti-Two-Block and Control Lock-Out System. Test daily for proper operation.

Two-blocking occurs when the load block (hook block, headache ball, rigging, etc.) comes into physical contact with the boom (boom nose, sheaves, boom extension, etc.). Twoblocking can cause hoist lines (wire rope), rigging, reeving, and other components to become highly stressed and overloaded in which case the wire rope may fail allowing the load, block, etc. to free fall.

Two-blocking is more likely to occur when both the main and auxiliary hoist lines are reeved over the main boom nose and b o o m e x t e n s i o n n o s e r e s p e c t i v e l y. A n o p e r a t o r, concentrating on the specific line being used, may telescope or lower the boom allowing the other hoist line attachment to contact the boom or boom extension nose, thus causing damage to the sheaves, or causing the wire rope to fail, dropping the lifting device to the ground and possibly injuring personnel working below.

Caution must be used when lowering the boom, extending the boom or hoisting up. Let out load line(s) simultaneously to prevent two-blocking the boom tip(s) and the hook block, etc. The closer the load is carried to the boom nose the more important it becomes to simultaneously let out wire rope as the boom is lowered. Keep load handling devices a minimum of 42 in (107 cm) below the boom nose at all times.

Load Moment Indication (LMI) Systems (If Equipped)

Two-blocking can be prevented. Operator awareness of the hazards of two-blocking is the most important factor in preventing this condition. An Anti-Two-Block System is intended to assist the operator in preventing dangerous twoblock conditions. It is not a replacement for operator awareness and competence.

Your crane may be equipped with an LMI system which is intended to aid the operator. Test daily for proper operation.

Never interfere with the proper functioning of operational aids or warning devices.

CRANE STABILITY/STRUCTURAL STRENGTH

(For cranes with center front stabiliers)

To avoid death or serious injury, ensure that the crane is on a firm surface with load and crane’s configuration within capacity as shown on the crane’s Load Chart and notes.

Ensure all pins and floats are properly installed and outrigger beams are properly extended before lifting on outriggers. On models equipped with outriggers that can be pinned at the mid-extend position (vertical strip, if applicable), the outriggers must also be pinned when operating from the midextend position.

Use adequate cribbing under outrigger floats to distribute weight over a greater area. Check frequently for settling.

SAFETY INFORMATION

RT765E-2 OPERATOR’S MANUAL

Carefully follow the procedures in this Operator’s Manual when extending or retracting the outriggers. Death or serious injury could result from improper crane setup on outriggers.

KEEP THE BOOM SHORT. Swinging loads with a long line can create an unstable condition and possible structural failure of the boom.

The operator must select the proper Load Chart and Load Moment Indicating (LMI) System program for the outrigger position selected.

Load Charts

Before swinging the superstructure over the side when the outriggers are retracted, check the Load Chart for backwards stability.

Long cantilever booms can create a tipping condition when in an extended and lowered position. Retract the boom proportionally with reference to the capacity of the applicable Load Chart.

Check crane stability before lifting loads. Ensure the outriggers (or tires if lifting on rubber) are firmly positioned on solid surfaces. Ensure the crane is level, brakes are set, and the load is properly rigged and attached to the hook. Check the Load Chart against the weight of the load. Lift the load slightly off the ground and recheck the stability before proceeding with the lift. Determine the weight of the load before you attempt the lift.

Unless lifting within On Rubber capacities, outrigger beams and jack cylinders (plus center front stabilizer, if equipped) must be properly extended and set to provide precise leveling of the crane. Tires must be clear of the ground before lifting on outriggers.

Load Charts represent the absolute maximum allowable loads, which are based on either tipping or structural limitations of the crane under specific conditions. Knowing the precise load radius, boom length, and boom angle should be a part of your routine planning and operation.

Actual loads, including necessary allowances, should be kept below the capacity shown on the applicable Load Chart.

Load Chart capacities are based on freely suspended loads.

You must use the appropriate Load Chart when determining the capability of the crane in the configuration required to perform the lift.

Maximum lifting capacity is available at the shortest radius, minimum boom length, and highest boom angle.

Do not remove the Load Charts from the crane.

Work Site Prior to any operation, you must inspect the entire work site, including ground conditions, where the crane will travel and operate. Be sure that the surfaces will support a load greater than the crane’s weight and maximum capacity.

Be aware of all conditions that could adversely affect the stability of the crane.

Wind Forces Wind can have a significant affect on loads that may be lifted by a crane. Wind forces act differently on a crane depending upon the direction from which the wind is blowing (e.g., wind on the rear of the boom can result in decreased forward stability, wind on the underside of the boom can result in decreased backward stability, wind on the side of the boom can result in structural damages, etc.). To assist you in determining prevailing wind conditions, refer to (Table 2-1).

Wind forces can exert extreme dynamic loads. Manitowoc recommends that a lift not be made if the wind can cause a loss of control in handling the load. Manitowoc recommends that, if the wind speed (velocity) is between 20 mph (32 km/h) to 30 mph (48 km/h), the load capacities shall be reduced to account for the size and shape of the load and the wind direction in relation to the machine for all boom and boom extension lengths. Further, operation of the crane in wind velocities over 30 mph (48 km/h) is not recommended.

Lifting Operations Before lifting, position the crane on a firm surface, properly extend and set the outriggers, and level the crane.

Depending on the nature of the supporting surface, adequate cribbing may be required to obtain a larger bearing surface.

Do not overload the crane by exceeding the capacities shown on the appropriate Load Chart. Death or serious injury could result from the crane tipping over or failing structurally from overload.

The crane can tip over or fail structurally if: •

The load and crane’s configuration is not within the capacity as shown on the applicable Load Chart and notes.

•

The ground is soft and/or the surface conditions are poor.

•

Outriggers are not properly extended and set. On models equipped with outriggers that can be pinned at the mid-extend position, the outriggers must also be pinned when operating from the mid-extend position.

•

Cribbing under the outrigger pads is inadequate.

Verify the crane’s capacity by checking the Load Chart against the weight of the load. Then, lift the load slightly at first to ensure stability before proceeding with the lift.

•

The crane is improperly operated.

Be sure the load is properly rigged and attached. Always determine the weight of the load before you attempt to lift it and remember that all rigging (slings, etc.) and lifting devices (hook block, boom extension, etc.) must be considered part of the load.

Be sure the hoist line is vertical before lifting. Do not subject the crane to side loading. A side load can tip the crane or cause it to fail structurally.

The crane is equipped with a bubble level that should be used to determine whether the crane is level. The load line can also be used to estimate the levelness of the crane by checking to be sure it is in-line with the center of the boom at all points on the swing circle.

If the boom extension, or auxiliary boom nose is to be used, ensure the electrical cable and the weight for the Anti-TwoBlo ck Swit ch are p rop erly ins ta lled an d t he LMI is programmed for the crane configuration. Refer to the LMI handbook supplied with the crane.

Measure the load radius before making a lift and stay within approved lifting areas based on the range diagrams and working area diagrams on the crane’s Load Chart.

Always keep the load as near to the crane and as close to the ground as possible.

Grove

Do not rely on the crane’s tipping to determine your lifting capacity.

Load Chart capacities are based on freely suspended loads.

Do not pull posts, pilings, or submerged articles. Be sure the load is not frozen or otherwise attached to the ground before lifting.

If you should encounter a tipping condition, immediately lower the load with the hoist line and retract or elevate the

SAFETY INFORMATION

RT765E-2 OPERATOR’S MANUAL

boom to decrease the load radius. Never lower or extend the boom; this will aggravate the condition.

Use tag lines whenever possible to help control the movement of the load.

When lifting loads, the crane will lean toward the boom and the load will swing out, increasing the load radius. Ensure the crane’s capacity is not exceeded when this occurs.

Do not strike any obstruction with the boom. If the boom should accidentally contact an object, stop immediately.

Inspect the boom. Remove the crane from service if the boom is damaged.

Never push or pull with the crane boom.

Avoid sudden starts and stops when moving the load. The inertia and an increased load radius could tip the crane over or cause it to fail structurally.

Use only one hoist at a time when lifting loads.

Always use enough parts-of-line to accommodate the load to be lifted. Lifting with too few parts-of-line can result in failure of the wire rope.

Counterweight On cranes equipped with removable counterweights, ensure the appropriate counterweight sections are properly installed for the lift being considered.

Do not add material to the counterweight to increase capacity. United States Federal law prohibits modification or additions which affect the capacity or safe operation of the equipment without the manufacturer’s written approval.

[29CFR 1926.1434]

Provided the crane is properly set up, the crane is in good working condition, that all operator’s aids are properly programmed, that the qualified crane operator adheres to the instructions found in the applicable Load Chart, Operator’s Manual and decals on the crane, the crane should not be unstable.

Multiple Crane Lifts Multiple crane lifts are not recommended.

Any lift that requires more that one crane must be precisely planned and coordinated by a qualified engineer.

If it is necessary to perform a multi-crane lift, the operator shall be responsible for assuring that the following minimum safety precautions are taken: •

Secure the services of a qualified engineer to direct the operation.

•

Use one qualified signal person.

•

Coordinate lifting plans with the operators, engineer, and signal person prior to beginning the lift.

•

Maintain communication between all parties throughout the entire operation. If possible, provide approved radio equipment for voice communication between all parties engaged in the lift.

•

Use cranes and rigging of equal capabilities and use the same boom length.

•

Use outriggers on cranes so equipped.

•

Be certain cranes are of adequate lifting capacity.

•

Calculate the amount of weight to be lifted by each crane and attach slings at the correct points for proper weight distribution.

•

Ensure the load lines are directly over the attach points to avoid side loading and transfer of loading from one crane to the other.

•

Do not travel. Lift only from a stationary position.

Outrigger Lift Off Regarding “lifting” of an outrigger pad during craning activities, be advised that the rated loads for these cranes, as indicated on the crane’s Load Chart, do not exceed 85% of the tipping load on outriggers as determined by SAE J765 OCT80 “Cranes Stability Test Code.” An outrigger pad may lift off the ground during operation of the crane within the capacity limits of the Load Chart, yet the crane will not have reached instability. The “balance point” for stability testing according to SAE and Manitowoc criteria is a condition of loading wherein the load moment acting to overturn the crane is equal to the maximum moment of the crane available to resist overturning. This balance point or point of instability for a crane does not depend on “lifting” of an outrigger but rather on comparison of the “opposing” load moments.

The occurrence of an outrigger lifting from the ground is often attributed to the natural flex in the crane’s frame. This may happen when lifting a load in certain configurations within the capacity limits of the Load Chart and is not necessarily an indication of an unstable condition.

2-8

ELECTROCUTION HAZARD To avoid death or serious injury, keep all parts of the crane, rigging and load at least 20 feet (6 meters) away from any e n e r g i z e d p o w e r l i n e . Yo u m u s t f o l l o w t h e O S H A requirements set forth in 29CFR 1926.1407 through 1926.1411.

This crane is not designed or equipped for use within 10 feet (3 meters) of energized power lines [Refer to 29CFR1926.1410 Table A]. If operation within 10 feet (3 meters) of any power lines cannot be avoided, the power utility must be notified and the power lines must be deenergized and grounded before performing any work.

Published 10-13-2011, Control # 364-03

RT765E-2 OPERATOR’S MANUAL If contact is ever accidentally made with a power line and any part of this crane, its rigging or load, never touch the crane or even approach or come near the crane.

SAFETY INFORMATION Electrocution can occur even without direct contact with the crane.

2

Crane operation is dangerous when close to an energized electrical power source. Exercise extreme caution and prudent judgement. Operate slowly and cautiously when in the vicinity of power lines.

Before operating this crane in the vicinity of electrical power lines or equipment, notify the power utility company. Obtain positive and absolute assurance that the power has been turned off.

This crane is not insulated. Always consider all parts of the load and the crane, including the wire rope, hoist cable, pendant cables, and tag lines, as conductors. You, the operator, are responsible for alerting all personnel of dangers associated with electrical power lines and equipment. Do not allow unnecessary personnel in the vicinity of the crane while operating. Permit no one to lean against or touch the crane. Permit no one, including riggers and load handlers, to hold the load, load lines, tag lines, or rigging gear.

If the load, wire rope, boom, or any portion of the crane contacts or comes too close to an electrical power source,

Grove

everyone in, on, and around the crane can be seriously injured or killed.

Most overhead power lines are not insulated. Treat all overhead power lines as being energized unless you have reliable information to the contrary from the utility company or owner.

The rules in this Operator’s Manual must be followed at all times, even if the electrical power lines or equipment have been de-energized.

The safest way to avoid electrocution is to stay away from electrical power lines and electrical power sources.

It is not always necessary to contact a power line or power source to become electrocuted. Electricity, depending on magnitude, can arc or jump to any part of the load, load line, or crane boom if it comes too close to an electrical power source. Low voltages can also be dangerous.

Thoroughly read, understand, and abide by all applicable federal, state, and local regulations.

SAFETY INFORMATION

RT765E-2 OPERATOR’S MANUAL

Set-Up and Operation During crane use, assume that every line is energized (“hot” or “live”) and take the necessary precautions.

Set up the crane in a position such that the load, boom, or any part of the crane and its attachments cannot be moved to within 20 ft (6 m) of electrical power lines or equipment. This includes the crane boom (fully extended to maximum height, radius, and length) and all attachments (boom extensions, rigging, loads, etc.). Overhead lines tend to blow in the wind so allow for lines’ movement when determining safe operating distance.

A suitable barricade should be erected to physically restrain the crane and all attachments (including the load) from entering into an unsafe distance from electrical power lines or equipment.

Plan ahead and always plan a safe route before traveling under power lines. Rider poles should be erected on each side of a crossing to assure sufficient clearance is maintained.

not assure that electrical contact will not occur. Even if codes or regulations require the use of such devices, failure to follow the rules listed here may result in serious injury or death. You should be aware that such devices have limitations and you should follow the rules and precautions outlined in this manual at all times even if the crane is equipped with these devices.

Insulating links installed into the load line afford limited protection from electrocution hazards. Links are limited in their lifting abilities, insulating properties, and other properties that affect their performance. Moisture, dust, dirt, oils, and other contaminants can cause a link to conduct electricity. Due to their capacity ratings, some links are not effective for large cranes and/or high voltages/currents.

The only protection that may be afforded by an insulated link is below the link (electrically downstream), provided the link has been kept clean, free of contamination, has not been scratched or damaged, and is periodically tested (just before use) for its dielectric integrity.

Boom cages and boom guards afford limited protection from electrocution hazards. They are designed to cover only the boom nose and a small portion of the boom. Performance of boom cages and boom guards is limited by their physical size, insulating characteristics, and operating environment (e.g. dust, dirt, moisture, etc.). The insulating characteristics of these devices can be compromised if not kept clean, free of contamination, and undamaged.

Proximity sensing and warning devices are available in different types. Some use boom nose (localized) sensors and others use full boom length sensors. No warning may be given for components, cables, loads, and other attachments located outside of the sensing area. Much reliance is placed upon you, the operator, in selecting and properly setting the sensitivity of these devices.

United States OSHA regulations require a flagman when operating in close proximity to energized power lines.

Appoint a reliable and qualified signal person, equipped with a loud signal whistle or horn and voice communication equipment, to warn the operator when any part of the crane or load moves near a power source. This person should have no other duties while the crane is working.

Tag lines should always be made of non-conductive materials. Any tag line that is wet or dirty can conduct electricity.

Do not store materials under power lines or close to electrical power sources.

Electrocution Hazard Devices The use of insulated links, insulated boom cages/guards, proximity warning devices, or mechanical limit stops does

2-10

Never rely solely on a device to protect you and your fellow workers from danger.

Some variables you must know and understand are: •

Proximity devices are advertised to detect the existence of electricity and not its quantity or magnitude.

•

Some proximity devices may detect only alternating current (AC) and not direct current (DC).

•

Some proximity devices detect radio frequency (RF) energy and others do not.

•

Most proximity devices simply provide a signal (audible, visual, or both) for the operator; this signal must not be ignored.

•

Sometimes the sensing portion of the proximity devices becomes confused by complex or differing arrays of power lines and power sources.

RT765E-2 OPERATOR’S MANUAL Do not depend on grounding. Grounding of a crane affords little or no p rotec tion f rom elect ric al h aza rds. The effectiveness of grounding is limited by the size of the conductor (wire) used, the condition of the ground, the magnitude of the voltage and current present, and numerous other factors.

Electrical Contact If the crane should come in contact with an energized power source, you must: 1.

Stay in the crane cab. Don’t panic.

2.

Immediately warn personnel in the vicinity to stay away.

3.

Attempt to move the crane away from the contacted power source using the crane’s controls which are likely to remain functional.

4.

Stay in the crane until the power company has been contacted and the power source has been de-energized.

No one must attempt to come close to the crane or load until the power has been turned off.

Only as a last resort should an operator attempt to leave the crane upon contacting a power source. If it is absolutely necessary to leave the operator’s station, jump completely clear of the crane. Do not step off. Hop away with both feet together. Do not walk or run.

Following any contact with an energized electrical source, the Manitowoc dealer must be immediately advised of the incident and consulted on necessary inspections and repairs. Thoroughly inspect the wire rope and all points of contact on the crane. Should the dealer not be immediately available, contact Manitowoc Crane Care. The crane must not be returned to service until it is thoroughly inspected for any evidence of damage and all damaged parts are repaired or replaced as authorized by your Manitowoc dealer or Manitowoc Crane Care.

Special Operating Conditions and Equipment Never operate the crane during an electrical thunderstorm.

When operating near transmitter/communication towers where an electrical charge can be induced into the crane or load: •

The transmitter shall be deenergized OR,

•

Tests shall be made to determine if an electrical charge will be induced into the crane or load.

•

The crane must be provided an electrical ground.

•

If taglines are used, they must be non-conductive.

•

Every precaution must be taken to dissipate induced voltages. Consult a qualified RF (radio frequency)

SAFETY INFORMATION Consultant. Also refer to local, state, and federal codes and regulations.

When operating cranes equipped with electromagnets, you must take additional precautions. Permit no one to touch the magnet or load. Alert personnel by sounding a warning signal when moving a load. Do not allow the cover of the electromagnet power supply to be open during operation or at any time the electrical system is activated. Shut down the crane completely and open the magnet controls switch prior to connecting or disconnecting magnet leads. Use only a non-conductive device when positioning a load. Lower the magnet to the stowing area and shut off power before leaving the operator’s cab (if equipped) or operator’s station.

PERSONNEL HANDLING The American Society of Mechanical Engineers issued a new American National Standard entitled, Personnel Lifting Systems, ASME B30.23-2005. This standard provides, “lifting and lowering of personnel using ASME B30 Standard hoisting equipment shall be undertaken only in circumstances when it is not possible to accomplish the task by less hazardous means.

Service and Repairs

SAFETY INFORMATION •

Do not attempt to repair or tighten any hydraulic hose or fitting while the engine is running, or when the hydraulic system is under pressure.

•

Never disconnect any hydraulic lines unless the boom is fully lowered, the engine is shut off, and the hydraulic pressure is relieved. To relieve hydraulic pressure, stop the engine and move the hydraulic controls in both directions several times.

•

Hot hydraulic fluid will cause severe burns. Wait for the fluid to cool before disconnecting any hydraulic lines.

•

Hydraulic fluid can cause permanent eye injury. Wear appropriate eye protection.

Moving Parts:

WARNING Fall Hazard!

Working at elevated heights without using proper fall protection can result in severe injury or death.

Always use proper fall protection as required by local, state or federal regulations.

Service and repairs to the crane must only be performed by a qualified person. All service and repairs must be performed in accordance with manufacturer’s recommendations, this manual, and the service manual for this machine. If there is any question regarding maintenance procedures or specifications, contact your Manitowoc dealer for assistance.

Qualified person is defined as one who by reason of knowledge, training and experience is thoroughly familiar with the crane’s operation and required maintenance as well as the hazards involved in performing these tasks.

Training and qualification of maintenance and repair personnel are crane owner’s responsibility.

Any modification, alteration, or change to a crane which affects its original design and is not authorized and approved

by Manitowoc is strictly prohibited. All replacement parts must be Manitowoc approved. Such action invalidates all warranties and makes the owner/user liable for any resultant accidents.

•

Do not place limbs near moving parts. Amputation of a body part may result. Turn off the engine and wait until the fan and belts stop moving before servicing crane.

•

Pinch points, which result from relative motion between mechanical parts, are areas of the machine that can cause personal injury or death. Do not place limbs or your body in contact with pinch points either on or around the machine. Care must be taken to prevent m o t i o n b e t w e e n p i n c h p o i n ts w h e n p e r f o r m i n g maintenance and to avoid such areas when movement is possible.

•

Do not allow persons to stand near extending or lowering outriggers. Foot crushing could occur

Before performing any maintenance, service or repairs on the crane: •

The boom should be fully retracted and lowered and the load placed on the ground.

•

Do not get under a raised boom unless the boom is blocked up safely. Always block up the boom before doing any servicing that requires the boom to be raised.

•

Stop the engine and disconnect the battery.

•

Controls should be properly tagged. Never operate the crane if it is tagged-out nor attempt to do so until it is restored to proper operating condition and all tags have been removed by the person(s) who installed them.

Hydraulic Fluid: •

•

Do not use your hand or any part of your body to check for hydraulic fluid leaks when the engine is running or the hydraulic system is under pressure. Fluid in the hydraulic system can be under enough pressure that it will penetrate the skin, causing serious injury or death.

Use a piece of cardboard, or piece of paper, to search for leaks. Wear gloves to protect your hands from spraying fluid.

If any hydraulic fluid is injected into the skin, obtain medical attention immediately or gangrene may result.

After maintenance or repairs: •

Replace all guards and covers that have been removed.

•

Remove all tags, connect the battery, and perform a function check of all operating controls.

•

Consult with Manitowoc Crane Care to determine if load testing is required after a structural repair is performed.

Lubrication The crane must be lubricated according to the manufacturer’s recommendations for lubrication points, time

intervals, and types. Lubricate at more frequent intervals when working under severe conditions.

Exercise care when servicing the hydraulic system of the crane, as pressurized hydraulic oil can cause serious injury.

The following precautions must be taken when servicing the hydraulic system: •

Follow the manufacturer’s recommendations when adding oil to the system. Mixing the wrong fluids could destroy seals, causing component failure.

•

Be certain all lines, components, and fittings are tight before resuming operation.

Tires

WARNING Possible equipment damage and/or personal injury!

Driving the crane with a tire and split-rim assembly under inflated at 80% or less of its recommended pressure can cause the wheel and/or tire to fail. Per OSHA Standard 1910.177(f)(2), when a tire has been driven under inflated at 80% or less of its recommended pressure, it must first b e c o m p l e t el y d e fl a t e d, r em o v ed f r o m t h e ax l e , disassembled, and inspected before re-inflation.

length of rope equal to thirty (30) times the rope diameter.

•

For running ropes other than rotation resistant: six (6) broken wires in one rope lay or three (3) broken wires in one strand.

•

One valley break where the wire fractures between strands in a running rope is cause for removal.

•

Abrasion of the rope resulting in wear of the individual outside wires of 1/3 of the original wire diameter.

•

Any kinking, bird caging, crushing, corrosion, or other damage resulting in distortion of the rope structure.

•

Rope that has been in contact with a live power line or has been used as a ground in an electric circuit (eg. welding) may have wires that are fused or annealed and must be removed from service.

•

In standing ropes, more than three (3) breaks in one rope lay in sections beyond the end connection or more than two (2) broken wires at an end connection.

•

Core deterioration, usually observed as a rapid reduction in rope diameter, is cause for immediate removal of the rope.

The following is a brief outline of the basic information required to safely use wire rope.

•

Wire ropes wear out. The strength of a wire rope begins to decrease when the rope is put to use and continues to decrease with each use. Wire rope will fail if worn-out, overloaded, misused, damaged or improperly maintained.

•

The nominal strength, sometimes called catalog strength, of a wire rope applies only to a new, unused rope.

•

The nominal strength of a wire rope should be considered the straight line pull which will actually break a new unused rope. The nominal strength of a wire rope should never be used as its working load.

•

Each type of fitting attached to a wire rope has a specific efficiency rating which can reduce the working load of the wire rope assembly or rope system.

•

Never overload a wire rope. This means never use the wire rope where the load applied to it is greater than the working load determined by the rope manufacturer.

Always make daily inspections of the wire rope, keeping in mind that all wire rope will eventually deteriorate to a point where it is no longer usable. Refuse to work with worn or damaged wire rope. Wire rope shall be taken out of service when any of the following conditions exist:

•

Never “shock load” a wire rope. A sudden application of force or load can cause both visible external and internal damage. There is no practical way to estimate the force applied by shock loading a rope. The sudden release of a load can also damage a wire rope.

•

•

Lubricant is applied to the wires and strands of a wire rope when it is manufactured. The lubricant is depleted when the rope is in service and should be replaced

Inspect the tires for nicks, cuts, embedded material, and abnormal wear.

Ensure all lug nuts are properly torqued.

Ensure pneumatic tires are inflated to the proper pressure (refer to the Load Chart). When inflating tires, use a tire gauge, clip-on inflator, and extension hose which will permit standing clear of the tire while inflating.

Wire Rope Use only the wire rope specified by Manitowoc as indicated on the crane’s Load Chart. Substitution of an alternate wire rope may require the use of a different permissible line pull and, therefore, require different reeving.

NOTE:

2-14

Wire rope may be purchased by contacting Manitowoc Crane Care.

For rotation-resistant running ropes: more than two (2) broken wires in a length of rope equal to six (6) times the rope diameter, or more than four (4) broken wires in a

•

•

In the U.S.A., regular inspections of the wire rope and keeping of permanent records signed by a qualified person are required by OSHA for almost every wire rope application. The purpose of the inspection is to determine whether or not a wire rope may continue to be safely used on the application. Inspection criteria, including number and location of broken wires, wear and elongation, have been established by OSHA, ANSI, ASME and similar organizations. See the Service Manual for inspection procedures.

SAFETY INFORMATION •

When a wire rope has been removed from service because it is no longer suitable for use, it must not be reused on another application.

When installing a new rope: •

Keep all parts of your body and clothing away from rotating hoist drums and all rotating sheaves.

•

Never handle the wire rope with bare hands.

•

Follow proper instructions for removing rope from a reel.

•

Apply back tension to the storage/payoff reel of the new rope to insure tight, even spooling onto the hoist drum.

When inspecting wire ropes and attachments, keep all parts of your body and clothing away from rotating hoist drums and all rotating sheaves. Never handle the wire rope with bare hands.

•

Operate the new rope - first through several cycles at light load and then through several cycles at intermediate load to allow the rope to adjust to operating conditions.

Some conditions that lead to problems in wire rope systems include:

When using a wedge socket:

-

Sheaves that are too small, worn or corrugated cause damage to a wire rope.

-

Broken wires mean a loss in strength.

-

Kinks permanently damage a wire rope and must be avoided.

-

Wire ropes are damaged by knots. Wire rope with knots must never be used.

-

Environmental factors such as corrosive conditions and heat can damage a wire rope.

-

Lack of lubrication can significantly shorten the useful life of a wire rope.

-

Contact with electrical wires and resulting arcing will damage a wire rope.

•

Always inspect socket, wedge, and pin for correct size and condition.

•

Do not use parts that are damaged, cracked, or modified.

•

Assemble the wedge socket with live end of rope aligned with the centerline of pin and assure proper length of tail (dead end) protrudes beyond the socket.

Sheaves

An inspection should include verification that none of the specified removal criteria for this usage are met by checking for such things as: -

Surface wear; nominal and unusual.

-

Broken wires; number and location.

-

Reduction in diameter.

-

Rope stretch (elongation).

-

Integrity of end attachments.

-

Evidence of abuse or contact with another object.

-

Heat damage.

-

Corrosion.

NOTE:

Grove

A more detailed wire rope inspection procedure is given in the Service Manual.

Inspect the boom nose and hook block sheaves for proper operation, excessive wear, and damage every 50 hours or weekly. Inoperable, damaged and/or worn sheaves cause rapid deterioration of wire rope.

Ensure sheaves carrying ropes that can be momentarily unloaded are equipped with close fitting guards or other devices to guide the rope back into the groove when the load is reapplied. Ensure sheaves in the lower load block are equipped with close fitting guards that will prevent the ropes from becoming fouled when the block is lying on the ground with loose ropes.

SAFETY INFORMATION

RT765E-2 OPERATOR’S MANUAL

To attain maximum wire rope life and minimize hook block rotation, it is recommended that even numbers of parts-ofline be used in multiple-part reeving whenever possible.

The use of nylon (nylatron) sheaves, as compared with metallic sheaves, may change the replacement criteria of rotation-resistant wire rope.

NOTE:

The use of cast nylon (nylatron) sheaves will substantially increase the service life of wire rope.

However, conventional rope retirement criteria based only upon visible wire breaks may prove inadequate in predicting rope failure. The user of cast nylon sheaves is therefore cautioned that a retirement criteria should be established based upon the user’s experience and the demands of his application.

Batteries Battery electrolyte must not be allowed to contact the skin or eyes. If this occurs, flush the contacted area with water and consult a doctor immediately.

When checking and maintaining batteries, exercise the following procedures and precautions: •

Wear safety glasses when servicing batteries.

•

If equipped, disconnect battery with the battery disconnect switch before disconnecting the ground battery cable.

•

Do not break a live circuit at the battery terminal.

Disconnect the ground battery cable first when removing a battery and connect it last when installing a battery.

•

Do not short across the battery posts to check charge.

Short circuit, spark, or flame could cause battery explosion.

•

Maintain battery electrolyte at the proper level. Check the electrolyte with a flashlight.

•

If applicable to your crane, check battery test indicator on maintenance-free batteries.

•

Check battery condition only with proper test equipment.

Batteries shall not be charged except in an open, wellventilated area that is free of flame, smoking, sparks, and fire.

Engine Fuel the crane only with the engine turned off. Do not smoke while fueling the crane. Do not store flammable materials on the crane.

Be familiar with the location and use of the nearest fire extinguisher.

Be careful when checking the engine coolant level. The fluid may be hot and under pressure. Shut down the engine and

2-16

allow the radiator time to cool before removing the radiator cap.

Shut down the engine and disconnect the battery before performing maintenance. If unable to do so for the task required, keep hands clear of the engine fan and other moving parts while performing maintenance.

Be careful of hot surfaces and hot fluids when performing maintenance on or around the engine.

Do not use ether to start the engine on cranes equipped with intake manifold grid heaters.

TRANSPORTING THE CRANE Before transporting the crane, check the suitability of the proposed route with regard to the crane height, width, length, and weight.

Check load limits of bridges on the travel route and ensure they are greater than the combined weight of the crane and transporting vehicle.

When loading or unloading the crane on a trailer or railroad car, use a ramp capable of supporting the weight of the crane.

Ensure the crane is adequately secured to the transporting vehicle.

Before transporting the crane on a road or highway, first check state and local restrictions and regulations.

When using hookblock tie downs, excessive loading can be applied by pulling the cable too tight, particularly when reeved with multiple part lines. When the cable is hooked into the hookblock tie down, the cable should be merely “snugged-up” with slack provided at the center line of sheave to anchor point. Care must be exercised anytime any crane function is being performed while the cable is hooked into the hookblock tie down. Do not draw cable taut.

TRAVEL OPERATION Only the crane operator shall occupy the crane when traveling.

When traveling, the boom should be completely retracted and lowered to the travel position and the turntable pin swing lock should be engaged. If equipped with boom rest, lower the boom into the boom rest and engage the turntable lock.

Strictly adhere to the guidelines and restrictions in the Load Chart for pick and carry operations.

This machine is manufactured with no axle suspension system. Traveling at high speeds, especially on rough ground, may create a bouncing affect that can result in loss of control. If bouncing occurs, reduce travel speed. (RT and Shuttle Lift Only)

RT765E-2 OPERATOR’S MANUAL Death or serious injury could result from being crushed by revolving tires.

“Stunt” driving and “horse-play” are strictly prohibited. Never allow anyone to hitch a ride or get on or off a moving crane.

SAFETY INFORMATION Check load limit of bridges. Before traveling across bridges, ensure they will carry a load greater than the crane’s weight.

If it is necessary to take the crane on a road or highway, check state and local restrictions and regulations.

Follow the instructions in this manual when preparing the crane for travel.

Keep lights on, use traffic warning flags and signs, and use front and rear flag vehicles when necessary. Check state and local restrictions and regulations.

If using a boom dolly/trailer, thoroughly read and understand all the steps and safety precautions in this manual for setup and travel.

Always drive the crane carefully obeying speed limits and highway regulations.

When driving the crane, ensure the cab is level, if equipped with a tilting cab.

Secure the hook block and other items before moving the crane.

Watch clearances when traveling. Do not take a chance of running into overhead or side obstructions.

When moving in tight quarters, post a signal person to help guard against collisions or bumping structures.

Stay alert at the wheel.

If equipped, ensure that the hoist access platform hand rail and step are in the travel configuration.

Slopes: -

Pick and carry on level surfaces only.

-

Refer to the Operation Section for more detailed information on traveling on slopes.

-

Driving across a slope is dangerous, as unexpected changes in slope can cause tip over. Ascend or descend slopes slowly and with caution.

-

Ascend or descend slopes with the boom pointing up the slope.

-

When operating on a downhill slope, reduce travel speed and downshift to a low gear to permit compression braking by the engine and aid the application of the service brakes.

Before traveling a crane, check suitability of proposed route with regard to crane height, width, and length.

Never back up without the aid of a signal person to verify the area behind the crane is clear of obstructions and/or personnel.

On cranes equipped with air-operated brakes, do not attempt to move the crane until brake system air pressure is at operating level.

•

Check for proper functioning of all controls and operator aids (e.g. LMI).

•

Check all braking (e.g. wheel, hoist, and swing brakes) and holding devices before operation.

WARNING

Never exit or enter the crane cab or deck by any other means than the access system(s) provided (i.e., steps and grab handles). Use the recommended hand-holds and steps to maintain a three-point contact when getting on or off the crane.

If necessary, use a ladder or aerial work platform to access the boom nose.

Do not make modifications or additions to the crane’s access system that have not been evaluated and approved by Manitowoc Crane Care.

Do not step on surfaces on the crane that are not approved or suitable for walking and working. All walking and working surfaces on the crane should be clean, dry, slip-resistant, and have adequate supporting capacity. Do not walk on a surface if slip-resistant material is missing or excessively worn.

Do not use the top of the boom as a walkway.

Do not step on the outrigger beams or outrigger pads (floats) to enter or exit the crane.

Use the hoist access platform (if equipped) when working in the hoist area.

Wear shoes with a highly slip-resistant sole material. Clean any mud or debris from shoes before entering the crane cab/ operator’s station or climbing onto the crane superstructure.

You must ensure that the outriggers and stabilizers are properly extended and set before performing any lifting operations. On models equipped with outriggers that can be pinned at the mid-extend position, the outriggers must also be pinned when operating from the mid-extend position.

Clear all personnel from the outrigger area before extending or retracting the outriggers. Carefully follow the procedures in this Operator’s Manual when extending or retracting the outriggers. Death or serious injury could result from improper crane set up on outriggers.

Be familiar with surface conditions and the presence of overhead obstructions and power lines.

Working Operator shall be responsible for all operations under his/her direct control. When safety of an operation is in doubt, operator shall stop the crane’s functions in a controlled manner. Lift operations shall resume only after safety concerns have been addressed or the continuation of crane operations is directed by the lift supervisor.

Know the location and function of all machine controls.

Make sure all persons are away from the crane and the Travel Select Lever is in the “N” (Neutral) position with the parking brake engaged before starting the engine.

RT765E-2 OPERATOR’S MANUAL

SAFETY INFORMATION

Sparks from the crane’s electrical system and/or engine exhaust can cause an explosion. Do not operate this crane in an area with flammable dust or vapors, unless good ventilation has removed the hazard.

Carbon monoxide fumes from the engine exhaust can cause suffocation in an enclosed area. Good ventilation is very important when operating the crane.

Before actuating swing or any other crane function, sound the horn and verify that all personnel are clear of rotating and moving parts.

Never operate the crane when darkness, fog, or other visibility restrictions make operation unsafe. Never operate a crane in thunderstorms or high winds.

2

Always be aware of your working environment during operation of the crane. Avoid contacting any part of the crane with external objects.

Clear all personnel from the counterweight and superstructure area before removing the counterweight.

Lifting

Keep unauthorized personnel clear of the working area during operation.

Only the crane operator shall occupy the crane when in operation.

You must always be aware of everything around the crane while lifting or traveling. If you are unable to clearly see in the direction of motion, you must post a look out or signal person before moving the crane or making a lift. Sound the horn to warn personnel

Use enough parts of line for all lifts and check all lines, slings, and chains for correct attachment. To obtain maximum lifting capacities, the hook block must be set up with enough parts of line. Too few parts of line can result in failure of the wire rope or hoist. No less than three wraps of wire rope should remain on the hoist drum. When slings, ties, hooks, etc., are used, make certain they are correctly positioned and secured before raising or lowering the loads.

Be sure the rigging is adequate before lifting. Use tag lines when possible to position and restrain loads. Personnel using tag lines should be on the ground.

Operate the crane only from the operator’s seat. Do not reach in a window or door to operate any controls.

Be sure good rigging practices are being used. Refuse to use any poorly maintained or damaged equipment. Never wrap the hoist cable around a load.

Operate the crane slowly and cautiously, looking carefully in the direction of movement.

If using a clam bucket, do not exceed 80% of the crane’s capacity.

A good practice is to make a “dry run” without a load before making the first lift. Become familiar with all factors peculiar to the job site.

Make certain the boom tip is centered directly over the load before lifting.

Ensure the wire rope is properly routed on the hook block and boom nose and that all rope guards are in place.

Grove

Ensure that all slings, ties, and hooks are correctly placed and secured before raising or lowering the load.

Be sure the load is well secured and attached to the hook with rigging of proper size and in good condition.

SAFETY INFORMATION

RT765E-2 OPERATOR’S MANUAL

Check the hoist brake by raising the load a few inches, stopping the hoist and holding the load. Be sure the hoist brake is working correctly before continuing the lift.

If the boom should contact an object, stop immediately and inspect the boom. Remove the crane from service if the boom is damaged.

When lowering a load always slow down the load’s descent before stopping the hoist. Do not attempt to change speeds on multiple-speed hoists while the hoist is in motion.

When lifting a load the boom may deflect causing the load radius to increase—this condition is made worse when the boom is extended. Ensure weight of load is within crane’s capacity on Load Chart.

Watch the path of the boom and load when swinging. Avoid lowering or swinging the boom and load into ground personnel, equipment, or other objects.

Lift one load at a time. Do not lift two or more separately rigged loads at one time, even if the loads are within the crane’s rated capacity.

Never leave the crane with a load suspended. Should it become necessary to leave the crane, lower the load to the ground and stop the engine before leaving the operator’s station.

Remember, all rigging equipment must be considered as part of the load. Lifting capacities vary with working areas. If applicable, permissible working areas are listed in the Load Chart. When swinging from one working area to another, ensure Load Chart capacities are not exceeded. Know your crane!

Avoid sudden starts and stops when moving the load. The inertia and an increased load radius could tip the crane over or cause it to fail structurally.

Use tag lines (as appropriate) for positioning and restraining loads. Check the load slings before lifting.

Be sure everyone is clear of the crane and work area before making any lifts.

Never swing over personnel, regardless of whether load is suspended from or attached to the boom.

Hand Signals A single qualified signal person shall be used at all times when: •

Working in the vicinity of power lines.

Stop the hook block from swinging when unhooking a load.

•

Swinging rapidly can cause the load to swing out and increase the load radius. Swing the load slowly. Swing with caution and keep the load lines vertical.

The crane operator cannot clearly see the load at all times.

•

Moving the crane in an area or direction in which the operator cannot clearly see the path of travel.

Look before swinging your crane. Even though the original setup may have been checked, situations do change.

Never swing or lower the boom into the carrier cab (if applicable).

Do not pull posts, pilings, or submerged articles. Be sure the load is not frozen or attached to the ground before lifting.

At all times use standardized hand signals - previously agreed upon and completely understood by the operator and signal person.

If communication with the signal person is lost, crane movement must be stopped until communications are restored.

Never push or pull loads with the crane’s boom; never drag a load.

Keep your attention focused on the crane’s operation. If for some reason you must look in another direction, stop all crane movement first.

Do not subject crane to side loading. A side load can tip the crane or cause it to fail structurally.

Obey a signal to stop from anyone.

BOOM EXTENSION To avoid death or serious injury, follow the procedures in this manual during erection, stowage, and use of the boom extension.

Install and secure all pins properly.

Control movement of boom extension at all times.

Do not remove right side boom nose pins unless boom extension is properly pinned and secured on front and rear stowage brackets.

DANGER Boom Extension Hazard!

To avoid death or serious injury, follow procedures in Load Chart, safety, and operation manuals during erection, stowage and use of boom extension. Install and secure all pins properly and control boom extension movement at all times.

Do not remove all the pins from both front and rear stowage brackets unless the boom extension is pinned to the right side of the boom nose.

When parking on a grade, apply the parking brake and chock the wheels.

Section 3 of this manual provides instructions for parking and securing a crane when it is to be left unattended. These instructions are intended to allow the crane to be placed in the most stable and secure position. However, Manitowoc recognizes that certain jobsite conditions may not permit the boom and boom extension of a crane to be fully lowered to the ground. When a qualified person at a jobsite determines that it is not practical to lower the boom to the ground, we recommend the following additional instructions be followed: •

The crane should be left in the smallest, most stable, valid operational configuration that the job site practically allows.

•

The crane can not be left running, with a load on the hook, or in erection mode, or in wind conditions in excess of allowed values.

•

The boom should be retracted as far as is practical, the crane configured in as stable a configuration as possible (boom angle, superstructure orientation, boom extension angle, etc.)

•

In high winds the boom and boom extensions should be lowered, or secured. Changing weather conditions including but not limited to: wind, ice accumulation, pr ec ip itat ion , floo ding , lig ht in g, e tc . s ho uld be c on s id e r e d w he n d et e r m i n i ng t h e l oc a ti o n a nd configuration of a crane when it is to be left unattended.

Properly inspect, maintain, and adjust boom extension and mounting.

When assembling and disassembling boom extension sections, use blocking to adequately support each section and to provide proper alignment.

SHUT-DOWN

Stay outside of boom extension sections and lattice work.

Use the following steps when shutting down the crane:

Watch for falling or flying pins when they are being removed.

•

Engage the parking brake.

•

Fully retract and lower the boom.

•

Engage the swing lock pin or 360 degree swing lock.

•

Place controls in neutral position.

•

Shut down the engine and remove the ignition key.

Tipping Hazard!

•

Chock the wheels, if not on outriggers.

When parking the crane and leaving it unattended follow the instructions in Section 3 of this manual.

•

Lock the operator’s cab (if applicable) and install vandal guards, if used.

PARKING AND SECURING

! WARNING

Failure to comply with these instructions may cause death or serious injury

2-22

In cold weather, never park the crane where the tires can become frozen to the ground.

Published 10-13-2011, Control # 364-03

RT765E-2 OPERATOR’S MANUAL COLD WEATHER OPERATION Cold weather operation requires additional caution on the part of the operator.

Check operating procedures in this manual for cold weather starting.

Don’t touch metal surfaces that could freeze you to them.

Clean the crane of all ice and snow.

Allow ample time for hydraulic oil to warm up.

In freezing weather, park the crane in an area where it cannot become frozen to the ground. The drive line can be damaged when attempting to free a frozen crane.

If applicable to your crane, frequently check all air tanks for water in freezing weather.

If applicable to your crane, always handle propane tanks according to the supplier’s instructions.

Never store flammable materials on the crane.

If cold weather starting aids are provided on your crane, use them. The use of aerosol spray or other types of starting fluids containing ether/volatiles can cause explosions or fire.

TEMPERATURE EFFECTS ON HYDRAULIC CYLINDERS Hydraulic oil expands when heated and contracts when cooled. This is a natural phenomena that happens to all liquids. The coefficient of expansion for API Group 1 hydraulic oil is approximately 0.00043 cubic inches per cubic inch of volume for 1°F of temperature change. Thermal contraction will allow a cylinder to retract as the hydraulic fluid which is trapped in the cylinder cools.

SAFETY INFORMATION larger difference in oil temperature verses the ambient temperature.

Thermal contraction coupled with improper lubrication or improper wear pad adjustments may, under certain conditions, cause a “stick-slip” condition in the boom. This “stick-slip” condition could result in the load not moving smoothly. Proper boom lubrication and wear pad adjustment is important to permit the boom sections to slide freely. Slow movement of the boom may be undetected by the operator unless a load is suspended for a long period of time. To minimize the effects of thermal contraction or “Stick-slip” it is recommended that the telescope control lever is activated periodically in the extend position to mitigate the effects of cooling oil.

If a load and the boom is allowed to remain stationary for a period of time and the ambient temperature is cooler than the trapped oil temperature, the trapped oil in the cylinders will cool. The load will lower as the telescope cylinder(s) retracts allowing the boom to come in. Also, the boom angle will decrease as the lift cylinder(s) retracts causing an increase in radius and a decrease in load height.

This situation will also occur in reverse. If a crane is set up in the morning with cool oil and the daytime ambient temperature heats the oil, the cylinders will extend in similar proportions.

(Table 2-2) has been prepared to assist you in determining the approximate amount of retraction/extension that may be expected from a hydraulic cylinder as a result of change in the temperature of the hydraulic oil inside the cylinder. The chart is for dry rod cylinders. If the cylinder rod is filled with hydraulic oil, the contraction rate is somewhat greater.

NOTE:

The change in the length of a cylinder is proportional to the extended length of the cylinder and to the change in temperature of the oil in the cylinder. For example, a cylinder extended 25 ft in which the oil cools 60°F would retract approximately 7 3/4 in (see chart below). A cylinder extended 5 feet in which the oil cools 60°F would only retract approximately 1 1/2 in. The rate at which the oil cools depends on many factors and will be more noticeable with a

Operators and service personnel must be aware that load movement, as a result of this phenomena, can be easily mistaken as leaking cylinder seals or faulty holding valves. If leaking seals or faulty holding valves are suspected to be the problem, refer to Service Bulletin dealing with testing telescope cylinders. (Bulletin 98-036 applies to TMS700 and bulletin G06-005A applies to RT890 and RT9130.

SAFETY INFORMATION

MODEL SPECIFIC INFORMATION

OVERLOAD INSPECTION

The RT765E-2 on rubber load charts has a minimum radius of 9.8 ft (3 m) with a load. Without a load, a radius of 8.2 ft (2.5 m) is safe for 360° on rubber. A radius of less than 8.2 ft (2.5 m) must be avoided on rubber because of backward stability considerations.

This information supplements the Load Moment Indicator (LMI) manual supplied with each Grove crane.

Ensure that the hoist access platform hand rail (1) (Figure 2-1) and step (2) (Fixed counterweight units only) are in the travel configuration. Remove pins from hand rail and rotate it down into the travel position, reinstall pins. Pull the step locking pin out, slide the step in to the travel position and release the lock pin.

When the LMI system has acknowledged an overload on your crane, you must carry out specified inspections on the crane.

These inspections apply only to overloads up to 50%. For overloads of 50% or higher, crane operation must be stopped immediately and Crane Care must be contacted for corrective action.

2 WARNING

1

Overload Hazard!

To avoid an accident caused by overload damage to your crane:

2

Perform the inspections outlined in this publication for overloads up to 50%.

•

Stop operating the crane and contact Manitowoc Crane Care immediately for overloads of 50% and higher.

NOTE: FIGURE 2-1

7649-20

•

Use the hoist access platform (1) (Figure 2-2) when working in the hoist area (Fixed counterweight units only).

If your crane is equipped with CraneSTAR, an overload warning will be posted to the web site for review by the crane owner.

Overload warnings do NOT indicate real time events! Warnings could be sent 24 hours (or more) after the actual event.

OPERATING CONTROLS AND PROCEDURES Test Mode Switch The Test Mode Switch (7) (Figure 3-2) is used when servicing the engines electronic control system. It is a two position on/off rocker switch used to activate the diagnostic mode (fault codes). The ignition switch must be ON but the engine not running. When the Test Mode Switch is ON, and is used in conjunction with the Idle/Diagnostic Mode Switch, access will be gained to scroll up or down through the fault codes.

Idle/Diagnostic Mode Switch The Idle/Diagnostic Mode Switch (8) (Figure 3-2) is a three position (+/-) momentary rocker switch that provides idlecontrol inputs that increases and decreases the engine idle (when the Test Mode Switch is in the OFF position) or scrolls up or down though the diagnostic mode fault codes when the test mode switch is in the ON position with the engine not running.

RT765E-2 OPERATOR’S MANUAL The Transmission Shift Lever (10) (Figure 3-2) is located on the right side of the steering column. The control lever operates the transmission selector valve electrically.

Positioning the lever up actuates forward and positioning the lever down actuates reverse. When the lever is in neutral, it rests in a detent. To move the lever up or down, pull back on the lever first. To shift the transmission to first, second, or third gear, rotate the knob to 1, 2, or 3.

The transmission has six forward gears and six reverse gears. To use the three low gears, put the Drive Axle switch at 4WD LO. To use the three high gears, put the Drive Axle switch at 2WD HI.

Press and release the top of the switch once to increase the engine to high idle. Press and release the bottom to return to low idle. Press and hold the switch, release when a predetermined idle speed is reached. Press the bottom to return to low idle.

Ignition Switch The Ignition Switch (9) is located on the right side of the steering column and under the transmission shift lever(10).

The switch is key-operated and has four positions: ACC [3], OFF [0], RUN [1], and START [2]. In the OFF position, all electrical power is off except for the lights controlled by the Headlights Switch, turn/hazard/stop lights, dome light and work light. Positioning the switch to ACC energizes all electrical components except for the start solenoid and engine ECM. Positioning the switch to RUN is the same as ACC, but the ignition circuit is also energized. Positioning the switch to START energizes the start relay, which in turn energizes the cranking motor solenoid and cranks the engine for starting. The switch is spring returned from START to RUN. To shut down the engine, position the switch to OFF. The Ignition switch has a mechanical anti-restart built into it.

If the engine does not start after the first attempt, the key switch must go to the OFF position and then back to START in order to try and start the engine another time.

WARNING

Passive: the exhaust is hot enough during normal working operation to burn off any hydrocarbon (soot) accumulation Active: Active self-regeneration occurs when there is not sufficient heat in the exhaust to convert all the hydrocarbon being collected in the DPF. Exhaust temperatures are raised by injecting a small amount of fuel. The resulting chemical reaction raises exhaust gas temperatures high enough to oxidize the hydrocarbon from the filter. This is all done without any operator intervention.

Manual: Manual or stationary, regeneration is the same as active regeneration but takes place while the equipment is not being operated. It offers the equipment operator the option, if needed, of performing regeneration outside the normal duty cycle.

RT765E-2 OPERATOR’S MANUAL

OPERATING CONTROLS AND PROCEDURES Although RT machines are specifically designed for rough terrain, the operator should be extremely cautious and aware of the terrain in which he is operating.

CAUTION Engine Damage Hazard!

If any warning light stays on or indicator(s) do not display proper readings, shut down the engine and correct the malfunction before resuming operation.

6.

Allow the engine to warm up at least five minutes before applying a load. Do not race the engine for a faster warm up.

Detailed cold weather starting and operating procedures are covered in the engine manual.

Idling the Engine Idling the engine unnecessarily for long periods of time wastes fuel and fouls injector nozzles. Unburned fuel causes carbon formation, oil dilution, formation of lacquer or gummy deposits on the valves, pistons, and rings, and rapid accumulation of sludge in the engine.

NOTE:

WARNING Tipping Hazard!

Avoid holes, rocks, extremely soft surfaces, and any other obstacles which might subject the crane to undue stresses or possible overturn.

Do not drive the crane with the boom off center because automatic oscillation lockout will occur, making the crane subject to tipping on uneven surfaces. Center the boom over the front, turn the Swing Brake Switch to ON and engage the Turntable Lock Pin (if equipped).

Fully retract the boom and ensure the swingaway jib is properly stowed and secured.

When prolonged idling is necessary, maintain at least 800 rpm.

Racing the Engine NEVER race the engine during the warm-up period. NEVER operate the engine beyond governed speed (as might occur in downhill operation or downshifting). Engine bearings, pistons, and valves may be damaged if these precautions are not taken.

Shutdown Procedure 1.

Allow the engine to operate at idle for about five minutes to avoid high internal heat rise and allow for heat dissipation.

2.

Turn the Ignition switch to OFF.

Crane Travel Operation

CAUTION Machine Damage Hazard!

Do not travel with an empty hook in a position where it can swing freely (except where noted). Either remove the hook block and/or headache ball from the hoist cable(s) and stow securely or make sure the hook block or headache ball is properly secured to the tie down provided for that purpose.

Do not drive the crane with the lift cylinder bottomed. At a minimum, position the boom slightly above horizontal.

Fully retract the outrigger stabilizers and properly store the floats.

Disengage the pumps (if applicable) for extended traveling.

CAUTION Machine Damage Hazard!

Engage the turntable lock pin for extended travel. Failure to engage the lock pin may allow the superstructure to swing uncontrolled, damaging the machine and/or property.

1.

With the Transmission Shift Lever in the neutral (N) position, start the engine and allow it to adequately warm up.

2.

Depress the Service Brake Foot Pedal.

3.

Position the Drive Axle Switch to either two-wheel high or four-wheel low.

CAUTION

CAUTION Possible Machine Damage!

Apply service brakes and bring crane to a complete stop before shifting transmission into reverse.

Steering Steering is accomplished by the steering wheel and the rear steer control. These controls, used singly or together, provide front wheel steering, rear wheel steering, four-wheel steering, and crabbing capabilities (Figure 3-14).

Front Wheel Steering Conventional front wheel steering is accomplished with the steering wheel. This method of steering should always be used when traveling at higher speeds.

Use four-wheel drive only when more traction is required.

NOTE: 4.

5.

If service brake hydraulic accumulator pressure is low, the parking brake cannot be released.

Lift the Transmission Shift Lever up out of its detent and push the lever to the forward (F) position, then rotate the Transmission Shift Lever Knob to the first (1) gear position. The gear selection “F1” will appear in the LCD Display to indicate that forward propulsion and first (1) gear have been selected; if the Service Brake Foot Pedal is not depressed prior to shifting to a gear, the gear selection will flash in the LCD Display until the Transmission Shift Lever is returned to the neutral (N) position and the transmission will not shift.

Release the Service Brake Foot Pedal and depress the Foot Throttle Pedal until maximum first gear speed is attained, then rotate the Transmission Shift Lever Knob to the second (2) gear position to continue to increase speed. For additional speed, continue shifting to a higher gear.

WARNING Unintensioned Operation Hazard!

Operate the rear steer ONLY at slow speeds for added job site maneuverability.

Rear Wheel Steering Rear wheel steering is controlled by the Rear Steer Control Switch. Moving the control switch to the desired position activates the rear steer cylinders, thereby steering the crane in the selected direction.

Four Wheel Steering Four wheel steering is accomplished with the steering wheel and the Rear Steer Control Switch. Depending upon which direction the operator wishes to travel, the steering wheel is turned opposite direction of the Rear Steer control position.

This allows the crane to turn or maneuver in close, restricted areas.

Crabbing

CAUTION Possible Machine Damage!

Do not downshift to a lower gear if the road speed is greater than the maximum speed of the lower gear.

Traveling — Reverse

Crabbing is accomplished with the steering wheel and the Rear Steer Control Switch. Depending upon which direction the operator wishes to travel (crab), the steering wheel is turned in the same direction as the Rear Steer Control Switch. This permits driving the crane forward or backward in a crabbing manner.

Traveling in reverse is accomplished the same way as traveling forward, except for shifting the Transmission Shift

6.

Return the Drive Axle Selector Switch to the two-wheel high position as soon as two-wheel traction will suffice and crane motion has stopped; again, the Service Brake Foot Pedal must be depressed and the Transmission Shift Lever must be in the neutral (N) position to shift from four-wheel low to two-wheel high.

Grove

The differential lock will not operate unless the Drive Selector Switch is in the four-wheel low position.

General The purpose of the differential lock is to provide maximum traction and control on poor road or highway surfaces. When the differential locks are actuated, the clutch collar completely locks the differential case, gearing, and axle shafts together, thus maximizing traction to both wheels of each axle. The lock position will also protect against spinout.

When normal driving conditions exist (during periods of good traction), the differential locks should not be actuated. The axles should be allowed to operate with differential action between both wheels.

Follow the steps below when engaging/disengaging the differential lock function.

1.

Lock the differentials by pressing and holding the Axle Differential Control Switch in the lock position; disengage the function by releasing the switch.

2.

Lock/unlock the differentials only when the vehicle is standing still or moving at a constant low speed with the wheels not slipping.

CAUTION Possible Machine Damage!

When driving on hard, dry surfaces with the differentials locked, do not turn the wheels. Damage to the drive line components can result.

Do not lock the differentials when the wheels are slipping.

Damage to the differentials can result.

3.

Locked differentials cause the crane’s turning radius to increase, creating an understeer condition; use caution, good judgement and drive at low speeds when operating the vehicle with lock differentials.

4.

Lock the differentials only when maximum traction is needed on poor road or highway surfaces.

OPERATING CONTROLS AND PROCEDURES

RT765E-2 OPERATOR’S MANUAL 1.

Ensure the tires are inflated to the recommended pressure. Refer to the Load Chart Book in the crane cab for proper inflation pressures.

2.

With the hook unloaded, the boom fully retracted and centered over the front at no more than a 10° to 15° boom angle, position the crane on a block or curb so that one rear tire is approximately 6 to 12 in (15 to 30 cm) above the level of the opposite tire.

3.

Slowly swing the superstructure to the left or right until the axle oscillation lockout valve is activated. This will lock the rear axle out of level. Do not swing beyond the tire track.

4.

After engaging the swing brake, slowly drive off of the block or curb and stop. The rear tires should both be touching the road surface and the opposite front tire should be light or slightly off the road surface.

5.

Release the swing brake and swing the superstructure until it is centered over the front.

CAUTION Possible Loss of Vehicle Stability!

Do not lock the differentials when the vehicle is traveling down steep grades and traction is minimal.

5.

Always unlock the differentials when the need for maximum traction has passed or when traveling on good road or highway surfaces.

Operation The differential lock function should preferably be engaged when the crane is stationary but may be engaged when moving, if the following conditions are met: 1.

The crane is moving very slowly (creep speed).

2.

The wheels are not spinning at the time of engagement.

When traveling with the differentials locked, do not deviate from a straight path more than is absolutely necessary.

Engage the differential locks by doing the following: 1.

Position the Axle Differential lock Control Switch to the locked position with the crane stationary or moving at a slow speed.

If moving at a slow speed, let up momentarily on the Foot Throttle Pedal to relieve torque on the differential gearing. This will fully engage the differential locks.

NOTE: 2.

When the differentials are locked, the Axle Differential Locked Indicator illuminates.

Proceed over the poor road condition cautiously.

When the adverse condition has passed, disengage the differential locks by doing the following: 1.

2.

Release the Axle Differential Lock control Switch, allowing it to return to the unlocked position while maintaining a slow speed.

Let up momentarily on the Foot Throttle Pedal to relieve torque on the differential gearing, allowing the differential to fully unlock.

NOTE: 3.

When the differentials are unlocked, the Axle Differential Locked Indicator will not be illuminated.

Resume driving at a normal speed using good driving judgement.

Axle Oscillation Lockouts Operation The following procedure should be used to periodically check the axle oscillation system and ensure that it is in proper working condition.

3-26

WARNING Tipping Hazard!

Do not operate the crane if the axle oscillation lockout system is not functioning properly.

Failure to comply with this warning may result in death or serious injury.

If the axle oscillation lockout valve is functioning properly, the crane will re-level itself; if the valve is not working properly, the crane will not re-level itself. If the rear axle does not lock or unlock properly, evaluate the lockout system and repair as necessary.

General Crane Operation Pump Drive The main hydraulic pumps are mounted on the torque converter drive pad. The pumps operate any time the engine is running.

Control Lever Operation The control lever operation for all crane functions is standard, i.e. the closer the lever is to neutral (center), the slower the system responds. The control lever should be returned to neutral to hold the load. Never feather the hoist control lever to hold the load.

NOTE:

Always operate the control levers with slow, even pressure.

RT765E-2 OPERATOR’S MANUAL

OPERATING CONTROLS AND PROCEDURES

Preload Check After the crane has been readied for service, an operational check of all crane functions (with no load applied) should be performed. The Preload Check is as follows: NOTE:

Operate engine at or near governed rpm during preload check of crane functions.

Carefully read and become familiar with all crane operating instructions before attempting a preload check or operating the crane under load.

1.

Extend and set outriggers.

2.

Raise, lower, and swing the boom a minimum of 45° right and left.

3.

Telescope the boom in and out.

4.

Raise and lower the cable a few times at various boom lengths. Ensure there is no kinking.

Using Your Load Chart NOTE:

One of the most important tools of every crane is the Load Chart found in the crane operator’s cab.

The Load Chart contains a large amount of information, which must be thoroughly understood by the operator.

The Load Chart contains outrigger capacity charts for fully extended, mid extended outriggers for the main boom and boom extension, and fully retracted outrigger beams for main boom only. In addition, the Load Chart contains two onrubber capacity charts: 360° stationary, and pick and carry over front.

Capacities above the line are structural strength limits and capacities below the line are stability limits.

The left column is the load radius, which is the distance from the center of crane rotation to the load center of gravity. The top row lists various boom lengths ranging from fully retracted to fully extended or boom extension lengths and offsets. The number at the intersection of the left column and top row is the total load capacity for that load radius and boom length or boom extension lengths offset. The number in parentheses below the total load capacity is the required boom angle (in degrees) for that load. When the boom length or lift radius or both are between values listed, the smallest load shown at either the next larger radius or next longer or shorter boom length shall be used.

Another important section is the range diagram. The range diagram shows the operating radius and tip height that can be achieved at a given boom length and angle. If the operator knows the radius and tip height required for a specific lift, the angle and boom length can be quickly determined from the range diagram. Or, if the boom length and angle are known, the tip height and operating radius can be quickly determined.

A lifting diagram is included to describe over side, over rear, and over front lifting areas. The lifting area diagram shows that the locations of the outrigger stabilizer cylinders in the fully extended position are used to mark the boundaries of the lifting areas.

A boom extension capacity chart and notes are included to list the capacities for the extension length, load radius, and boom angle.

Another section contains the notes for lifting capacities. Be sure to read and understand all the notes concerning lifting capacities.

The load chart also gives weight reductions for load handling devices such as hook blocks, headache balls, boom extensions, etc., which must be taken into consideration as part of the load. Remember, the weight of any other load handling devices such as chains, slings, or spreader bars must be added to the weight of the load.

Proper Leveling of the Crane ASME B30.5 specifies that if a crane is not level within 1% of grade, the allowable capacities must be reduced. Therefore, whether lifting on rubber or outriggers, it is essential that the crane is level to within 1% of grade. The bubble level that is provided on the crane is calibrated to be accurate within 1% of grade.

FIGURE 3-15 The Load Charts are divided into structural strength and stability limits. This is shown by the bold line across the chart.

Grove

To properly level the crane, the boom must be positioned over the front of the crane, fully lowered to horizontal and fully retracted (for cranes fitted with a boom rest, the boom shall be stowed onto the rest). Raise and level the crane using the outriggers; refer to Setting the Outriggers, page 328.

Bubble Level Adjustment

If extending the outrigger to the mid-extend or fully extended position, depress the desired Extension Switch on the Outrigger Selector Panel and hold the Outrigger Extension/Retraction Switch to EXTEND. The appropriate outrigger beam begins to extend. Refer to Engaging the Mid-Extend Lock Pin, page 3-29 if the crane is to be operated with any outrigger at the midextend position.

The bubble level adjustment should be checked periodically; if it is suspected that the bubble level indicator is out of adjustment, verify and adjust the bubble level as follows: 1.

Locate the crane on a firm, level surface.

2.

Extend and set the outriggers. Level the crane, as indicated by the bubble level indicator, using the outriggers.

3.

Place a miracle pointer level, carpenter level, or similar type device on a machined surface such as the turntable bearing or bearing mounting surfaces.

4.

Using the outriggers, level the crane as indicated on the leveling device used in step 3.

5.

Using the bubble level indicator mounting screws, adjust the bubble level indicator to show level.

WARNING Tipping Hazard!

All four outrigger beams must be deployed to one of three positions before beginning operation, which include fully retracted, mid-extend, or fully extended; do not operate the crane with the outriggers in any other position.

4.

Crane Functions Setting the Outriggers 1.

Engage the Parking Brake.

NOTE: 2.

CAUTION Possible Equipment Damage!

Always depress one of the outrigger/selector switches before positioning the outrigger extension/retraction switch to extend or retract. Failure to do this may cause a hydraulic lock against the individual solenoid valves, preventing them from opening.

After deploying the four outrigger beams to one of the three proper positions (fully retracted, mid-extend, fully extended), depress the desired Stabilizer Switch on the Outrigger Selector Panel and hold the Outrigger Extension/Retraction Switch to EXTEND. The appropriate stabilizer begins to move.

Extend each s tabilizer, positi oning the float as necessary, until the locking levers of the float engage the stabilizer cylinder barrel.

The Parking Brake must be engaged to enable outrigger functions.

Position the outrigger floats directly out from each outrigger to where the outriggers will be properly extended.

NOTE:

More than one stabilizer can be extended at a time.

5.

Extend the front stabilizers approximately 3 to 4 in (8 to 10 cm).

6.

Extend the rear stabilizers approximately 3 to 4 in (8 to 10 cm).

NOTE: 7.

If crane is equipped with tilting cab, ensure cab is in the lowered position before leveling machine.

Repeat step 4 until all wheels are clear of the ground and the crane is level as indicated by the bubble level indicator located on the right side of the cab.

NOTE:

WARNING

More than one outrigger beam can be extended at a time. However, to ensure that each outrigger is fully extended, repeat step 3 for each outrigger after a multi-outrigger extension.

If it is suspected that the bubble level indicator is out of adjustment, verify and adjust the bubble level using the procedures under Bubble Level Adjustment, page 3-28.

OPERATING CONTROLS AND PROCEDURES 2.

WARNING Tipping Hazard!

The mid-extend outrigger beam lock pin must be engaged before operating on any beam from the mid-extend position.

For cranes not equipped with an Outrigger Monitoring System, the operator must select the proper load chart and LMI program for the outrigger position selected.For cranes not equipped with an Outrigger Monitoring System, the operator must select the proper load chart and LMI program for the outrigger position selected.

NOTE:

For cranes equipped with an Outrigger Monitoring System, outrigger positions are automatically monitored through the LMI. Refer to Outrigger Monitoring System (OMS) (Optional—Standard in North America), page 3-29.

Outrigger Monitoring System (OMS) (Optional—Standard in North America)

Slowly extend or retract the outrigger beam, allowing the locking pin to drop into the hole in the top of the outrigger beam, engaging the outrigger beam at the desired length.

Stowing the Outriggers 1.

Select the rear stabilizers with the Stabilizer Selector switches and hold the Extension/Retraction switch to RETRACT until the rear stabilizers have retracted several inches.

2.

Select the front stabilizer with the Stabilizer Selector switches and hold the Extension/Retraction switch to RETRACT until the front stabilizers have retracted several inches.

3.

Repeat steps 1 and 2 until the crane is resting on all four wheels and the stabilizer floats are several inches off the ground

CAUTION Crushing Hazard!

Keep feet and hands clear of floats when unlocking the floats from the stabilizers.

The Outrigger Monitoring System (OMS) aids the operator in accurately programming the Load Moment Indicator (LMI) by automatically identifying the position of each outrigger beam.

The OMS uses four sensors, one per outrigger beam, to identify when an outrigger beam is positioned to one of three pre-defined locations, including fully retracted, mid-extend, and fully extended.

NOTE: 4.

Set up of the outriggers is the same for cranes equipped with OMS; refer to Setting the Outriggers, page 3-28. The LMI only indicates the position of the outrigger beam and should not be used to deploy the beam.

Release the locking levers and allow the floats to drop to the ground.

5.

Continue to retract the stabilizers until they are fully retracted.

6.

Depress the desired Extension rocker switch on the Outrigger Selector panel and hold the outrigger Extension/Retraction rocker switch to RETRACT. The appropriate outrigger beam should begin to retract.

If the crane is setup on outriggers and “On Outriggers” is chosen when programming the LMI, then the OMS indicates to the LMI the position of each of the four outrigger beams.

Based on this information, the LMI will choose the most conservative outrigger beam configuration (i.e. If three outriggers are fully extended and one is retracted, the LMI will select retracted as the outrigger configuration). A confirmation of this outrigger configuration is all that is needed. Refer to the Load Moment Indicator Operator’s Handbook for detailed instructions.

NOTE: 7.

Stowing the Mid-Extend Lock Pin 1.

1.

NOTE:

NOTE:

Grove

It may be necessary to jog the outrigger extension/ retraction switch slightly to ensure proper pin engagement.

After all outriggers have been fully retracted, stow the outrigger floats.

Engaging the Mid-Extend Lock Pin Turn the locking pin 90° from its stowed position and allow the pin to rest on top of the outrigger beam.

Each stabilizer float weighs approximately 70 lb (32 kg).

2.

Retract the outrigger extension/retraction cylinder.

If the lock pin is wedged in the hole in the outrigger beam, it may be necessary to jog the outrigger extension/retraction switch slightly while pulling upward on the pin.

Lift the lock pin and turn it 90° to its stowed position.

WARNING

WARNING

Crushing Hazard!

Crushing and/or Tipping Hazard!

Death or serious injury could result from being crushed by moving machinery. Before activating swing, sound the horn and verify that all personnel are clear of rotating and moving parts.

Keep the area beneath the boom clear of all obstructions and personnel when lowering the boom.

Keep the area beneath the boom clear of all obstructions and personnel when lowering the boom.

The operator must select the proper load chart and LMI program for the outrigger position selected.

CAUTION Machine Damage!

Never push or pull the swing control lever through neutral to the opposite direction to stop swing motion. Use the swing brake foot pedal to stop swing rotation.

NOTE:

Automatic rear axle oscillation lockout will activate when the boom swings right or left of the crane centerline.

To swing the boom, the SWING control lever is pushed forward, away from the operator, to swing CLOCKWISE, or p u l l e d b a c k , t o w a r d t h e o p e r a t o r, t o s w i n g COUNTERCLOCKWISE. Always operate the control lever with a slow, even pressure. Use the swing brake foot pedal to stop rotation, then position the swing brake switch to ON to prevent further rotation.

Elevating the Boom

Long cantilever booms can create a tipping condition, even when unloaded and in an extended, lowered position.

CAUTION Machine Damage!

When lowering the boom, simultaneously let out the hoist cable to prevent two-blocking the boom nose and hook block.

The closer the load is carried to the boom nose, the more important it becomes to simultaneously let out the hoist cable as the boom is lowered.

To lower the boom, push the Boom Control Lever forward, away from the operator, and hold until the boom is lowered to the desired position.

Extending the Boom

WARNING Crushing Hazard!

Check the load chart for the maximum load at a given radius, boom angle, and length before extending the boom with a load.

CAUTION

WARNING Crushing Hazard!

Keep the area above and below the boom clear of all obstructions and personnel when elevating the boom.

To elevate the boom, pull the BOOM (lift) control lever back, toward the operator, and hold until the boom reaches the desired elevation level.

Machine Damage!

Before extending the boom, ensure the large access cover on top of the boom base section is installed.

When extending the boom, simultaneously let out the hoist cable to prevent two-blocking the boom nose and hook block.

NOTE:

The telescope function is controlled by a foot pedal if the crane is equipped with an auxiliary hoist.

To extend the boom, push on the top of the Telescope Control foot pedal.

WARNING

WARNING

To retract the boom, push on the bottom of the Telescope Control Foot Pedal.

Unexpected Operation Hazard!

Electronic equipment on this crane is intended as an aid to the operator. Under no condition should it be relied upon to replace the use of capacity charts and operating instructions. Sole reliance upon these electronic aids in place of good operating practices can cause an accident.

Lowering and Raising the Hoist Cable

Load Moment Indicator (LMI) System

Crushing Hazard!

When retracting the boom, the load will lower unless the hoist cable is taken in at the same time

WARNING Crushing Hazard!

Keep the area beneath the load clear of all obstructions and personnel when lowering or raising the cable (load).

Do not jerk the control lever when starting or stopping the hoist. Jerking the lever causes the load to bounce, which could result in possible damage to the crane.

NOTE:

When the load is stopped at the desired height, the automatic brake will engage and hold the load as long as the control lever remains in neutral.

Lowering the Cable Push the Main or Aux hoist control lever forward, away from the operator, and hold until the hook or load is lowered to the desired height.

Raising the Cable Pull the Main or Aux hoist control lever back, toward the operator, and hold until the hook or load is raised to the desired height.

Hoist Speed Range Selection

CAUTION

The Load Moment Indicator (LMI) is an electro-mechanical sensing system designed to alert the crane operator of impending capacity when the system has been properly preset by the operator. The control panel is mounted in the front console of the operator’s cab. When an overload condition is sensed, the system provides the operator with a visual and audible warning, and locks out the control levers to prevent lowering the boom, extending the boom, or raising the main or auxiliary hoist cables.

Three additional features are included within the LMI system: •

Swing Angle Set Limitation

•

Work Area Definition

•

Anti-two Block Device

Swing Angle Set Limitation allows left and right swing angle to be preset. When the preset angle is reached, the system will provide an audible warning.

Work Area Definition allows the crane operator to describe the crane’s working area by setting up “virtual walls”. They are referred to as virtual walls because they exist in the system and are not real walls. The virtual walls represent obstacles (i.e. buildings, towers, poles, etc.) in the crane’s working range. They are set by defining points along the outer limits of the working area with the tip of the boom. Once the working area has been defined, the system will provide a visual and an audible warning if the boom approaches a virtual wall.

Equipment Damage!

Do not change the hoist speed range with the hoist rotating.

To change the speed range of the hoist(s), position the applicable switch (Main Hoist Speed or optional Aux Hoist Speed) to HIGH or LOW as applicable

Grove

CAUTION Possible Machine Damage!

When defining virtual wall(s), always allow a safe working distance to any obstacles. Never work outside a safe working area as defined by common practice, standards, and manuals.

OPERATING CONTROLS AND PROCEDURES

WARNING Risk of Unexpected Operation!

There are no machine cutouts associated with the swing angle set limitation or the work area definition features.

An Anti-Two Block Device is also incorporated into the system to prevent the hook block or headache ball from coming into contact with the boom nose or boom extension.

This condition will cause a lockout of hoist up, boom down, and telescope out, and also provide a visual and an audible alarm.

Refer to the LMI Operator’s Handbook for more detailed information on the function of the LMI system.

Control Lever Lockout System The control lever lockout system consists of hydraulic solenoid valves (located in the directional control valves) which are in series between the hydraulic remote control valves in the cab and the pilot-operated directional control valves. When the valves are actuated, they prevent pilot flow between the hydraulic remote control valve in the cab and the appropriate directional control valve. The valves are activated in such a manner as to prevent worsening the condition, i.e. boom down, telescope out, or hoist up. The control lever lockout system is used with the anti-two-block system or the load moment indicator (LMI) system.

block (Figure 4-7) and (Figure 4-8). This reeving should be accomplished by a qualified rigger using standard rigging procedures.

When assembly is complete, raise the boom to a working position with a load suspended to firmly seat the wedge and rope into the socket before the crane is used operationally.

In order to quick reeve the hook block without removing the wedge socket on the end of the cable refer to Figure 4-4.

CAUTION If the socket is not positioned with the flat face toward the boom sections, structural damage will occur.

FIGURE 4-4 FIGURE 4-5

DEAD-END RIGGING/WEDGE SOCKETS Wedge socket assemblies are popular rigging accessories and have been successfully used for decades to terminate wire ropes on mobile cranes. A wedge socket assembly is easily installed and dismantled but it must be installed and used correctly. It is essential to use only a wedge and socket of the correct size for the rope fitted. Failure to do so may result in the rope pulling through the fitting.

Since state and local laws may vary, alternate attachment methods may be necessary depending upon work conditions. If alternate methods are selected, the user is responsible and should proceed in compliance with the regulations in force. If there are any questions, contact your local Manitowoc Distributor or Manitowoc Crane Care

When anchoring the socket to the boom, ensure the flat face of the socket is in position, as shown, toward the boom sections (Figure 4-5).

INSTALLING WEDGE AND SOCKET 1.

Inspect the wedge and socket. Remove any rough edges and burrs.

2.

The end of the wire rope should be seized using soft, or annealed wire or strand. If the end of the rope is welded, the welded end should be cut off. This will allow the distortion of the rope strands, caused by the bend around the wedge, to adjust themselves at the end of the line.

Do not mix components from different manufacturers. The selection, installation and use of a wedge socket assembly must be in accordance with the requirements of the wedge socket manufacturer and the wire rope manufacturer upon whose wire rope the wedge socket assembly will be used.

Grove specifies the size, type, class and line pulls for wire rope, predominately rotation resistant wire rope, and rigging accessories such as overhaul balls and hook blocks for use with each new crane that it manufactures. Other wire ropes and rigging accessories are available from various vendors.

D i ff e r e n t w i r e r o p e m a n u f a c t u r e r s h a v e d i ff e r i n g requirements for the construction, handling, cutting, seizing, installation, termination, inspection and replacement of the wire ropes they produce.

the rope will bend as it leaves the socket, and the edge of the socket will wear into the rope causing damage to the rope and eventual failure.

4.

Insert the end of a wire rope into the socket, form a loop in the rope, and route the rope back through the socket allowing the “dead” end to protrude from the socket.

Ensure the dead end of the rope is of sufficient length to apply end treatment to the dead end after the wedge has been seated.

5.

Insert the wedge into the loop and pull the live end of the rope until the wedge and rope are snug inside the socket. It is recommended that the wedge be seated inside the socket to properly secure the wire rope by using the crane’s hoist to first apply a light load to the live line.

6.

After final pin connections are made, increase the loads gradually until the wedge is properly seated.

7.

The wire rope and wedge must be properly secured inside the socket before placing the crane into lifting service. It is the wedge that secures the wire rope inside the socket whereas the dead-end treatment is used to restrain the wedge from becoming dislodged from the socket should the rope suddenly become unloaded from the headache ball or hook block striking the ground, etc.

Sketches A through F (Figure 4-7) illustrate various methods for treating the dead-ends of wire ropes which exit a wedge socket assembly. While use of the loop-back method is acceptable, care must be exercised to avoid the loop b ec o m i n g e n ta n g l e d w i t h t r e e br a nc h e s a nd o t he r components during crane transport and with the anti-two block system and other components during use of the crane.

Of the methods shown below, Grove prefers that method A or F be used on Grove cranes, i.e., clipping a short piece of wire rope to the dead-end or using a commercially available specialty clip or wedge. Typically, it is recommended that the tail length of the dead-end should be a minimum of 6 rope diameters but not less that 6 in (15.2 cm) for standard 6 to 8 strand ropes and 20 rope diameters but not less than 6 in (15.2 cm) for rotation resistant wire ropes.

When using method A, place a wire rope clip around the dead end by clamping a short extra piece of rope to the rope

GENERAL Following the designated lubrication procedures is important in ensuring maximum crane lifetime and utilization. The procedures and lubrication charts in this section include information on the types of lubricants used, the location of the lubrication points, the frequency of lubrication, and other information.

ENVIRONMENTAL PROTECTION Dispose of waste properly! Improperly disposing of waste can threaten the environment.

Potentially harmful waste used in Manitowoc cranes includes — but is not limited to — oil, fuel, grease, coolant, air conditioning refrigerant, filters, batteries, and cloths which have come into contact with these environmentally harmful substances.

Handle and dispose of waste according to local, state, and federal environmental regulations.

When filling and draining crane components, observe the following: •

Do not pour waste fluids onto the ground, down any drain, or into any source of water.

Grove

•

Always drain waste fluids into leak proof containers that are clearly marked with what they contain.

•

Always fill or add fluids with a funnel or a filling pump.

•

Immediately clean up any spills.

LUBRICATION INTERVALS The service intervals specified are for normal operation where moderate temperature, humidity, and atmospheric conditions prevail. In areas of extreme conditions, the service periods and lubrication specifications should be altered to meet existing conditions. For information on extreme condition lubrication, contact your local Manitowoc Distributor or Manitowoc Crane Care.

CAUTION Possible Equipment Damage!

Chassis grease lubricants must not be applied with air pressure devices as this lubricant is used on sealed fittings.

The multipurpose grease installed during manufacture is of a lithium base. Use of a noncompatible grease could result in damage to equipment.

All Weather Package & Lubricants

In general, petroleum based fluids developed especially for low temperature service may be used with satisfactory results. However, certain fluids, such as halogenated hydrocarbons, nitro hydrocarbons, and phosphate ester hydraulic fluids, might not be compatible with hydraulic system seals and wear bands. If you are in doubt about the suitability of a specific fluid, check with your authorized Manitowoc distributor or Manitowoc Crane Care.

Engineering recommends the following lubricants for components for ambient temperatures to -40°F. Special lubricants alone are not sufficient to operate at extreme low temperatures. We also recommend the use of appropriately sized heaters for the hydraulic tank, engine oil pan, engine jacket water and batteries. The operator needs to follow the guide lines as stated in the operator’s manual. We assume that the customer has taken steps for use of an appropriate engine antifreeze coolant, and has taken into consideration the fuel, fuel system and starting system. And, has done whatever they feel necessary to add insulation for under hood temperatures and meet the engine manufacture's intake air temperature. Other lubricants may be used if they meet the specification of the lubricant that is requested.

Please consult factory.

NOTE:

All fluids and lubricants may be purchased by contacting Manitowoc Crane Care Parts Department.

Regardless of temperature and oil viscosity, always use suitable start-up procedures to ensure adequate lubrication during system warm-up.

Surface Protection for Cylinder Rods Steel cylinder rods include a thin layer of chrome plating on their surfaces to protect them from corroding. However, chrome plating inherently has cracks in its structure which can allow moisture to corrode the underlying steel. At typical ambient temperatures, hydraulic oil is too thick to penetrate these cracks. Normal machine operating temperatures will allow hydraulic oil to warm sufficiently to penetrate these cracks and if machines are operated daily, protect the rods.

Machines that are stored, transported, or used in a corrosive environment (high moisture, rain, snow, or coastline conditions) need to have the exposed rods protected more frequently by applying a protectant. Unless the machine is operated daily, exposed rod surfaces will corrode. Some cylinders will have rods exposed even when completely retracted. Assume all cylinders have exposed rods, as corrosion on the end of the rod can ruin the cylinder.

Premix 60/40

Manitowoc Crane Care has Boeshield® T-9 Premium Metal Protectant available in 12 oz. aerosol cans by ordering part number 9999101803 through the Parts Department.

Cylinder operation and inclement weather will remove the Boeshield® protectant; therefore, inspect machines once a week and reapply Boeshield® to unprotected rod

WIRE ROPE LUBRICATION Wire rope is lubricated during manufacturing so that the strands, and individual wires in strands, may move as the rope moves and bends. A wire rope cannot be lubricated sufficiently during manufacture to last its entire life.

Therefore, new lubricant must be added periodically throughout the life of a rope to replace factory lubricant which is used or lost. For more detailed information concerning the lubrication and inspection of wire rope, refer to Wire Rope in Section 1- Introduction in the Service Manual.

It is recommended that all exposed cylinder rods be protected using Boeshield® T-9 Premium Metal Protectant.

LUBRICATION

LUBRICATION POINTS A regular frequency of lubrication must be established for all lubrication points. Normally, this is based on component operating time. The most efficient method of keeping track of lube requirements is to maintain a job log indicating crane usage. The log must use the engine hourmeter to ensure coverage of lube points that will receive attention based on their readings. Other lubrication requirements must be made on a time basis, i.e. weekly, monthly, etc.

All oil levels are to be checked with the crane parked on a level surface in transport position, and while the oil is cold, unless otherwise specified.

On plug type check points, the oil levels are to be at the bottom edge of the check port.

On all hoists with a check plug in the drum, the fill plug shall be directly on top of the hoist, and the check plug level.

All grease fittings are SAE Standard unless otherwise indicated. Grease non-sealed fittings until grease is seen extruding from the fitting. One ounce(28 grams) of EP-MPG equals one pump on a standard one pound (0.45 kg) grease gun.

will provide the necessary lubrication and help prevent the formation of rust. An Anti-Seize compound may be used if rust has not formed, otherwise the component must be cleaned first.

Grease fittings that are worn and will not hold the grease gun, or those that have a stuck check ball, must be replaced.

Where wear pads are used, cycle the components and relubricate to ensure complete lubrication of the entire wear area.

CraneLUBE Manitowoc highly recommends the use of CraneLUBE l u b r i c a n ts t o i n c r e a s e y o u r c r a n e ’s r e l i a b i l i t y a n d performance. Contact your Manitowoc Distributor for information about the Manitowoc’s CraneLUBE lubrication program.

Safety To lubricate many of the locations the engine will need to be started. After positioning areas of the unit for lubrication the engine must be turned off and the moved areas stable before approaching.

Over lubrication on non-sealed fittings will not harm the fittings or components, but under lubrication will definitely lead to a shorter lifetime.

On sealed U-joints, care must be exercised to prevent rupturing seals. Fill only until expansion of the seals first becomes visible.

Unless otherwise indicated, items not equipped with grease fittings, such as linkages, pins, levers, etc., should be lubricated with oil once a week. Motor oil, applied sparingly,

WARNING Crushing Hazard!

Movement of the superstructure and the boom may create a crushing and/or pinching hazard. Failure to observe this warning could result in death or serious injury if the message is ignored.

NOTE: • Check fluid level with engine running at 1000 rpm idle and the oil at 150 to 200 ° F (65 to 93° C). Do not attempt an oil level check with cold oil. To bring the oil temperature to this range, it is necessary to either work the crane or stall the converter. Converter stall should be accomplished by engaging shift lever in forward high range with the brakes applied and then accelerating the engine to half or three-quarter throttle. Hold the stall until the required converter temperature is reached and stabilized.

Do not operate the converter at stall condition for longer than 30 seconds at one time. Shift to neutral for 15 seconds and repeat the procedure until the desired temperature is reached. Excessive temperature, i.e, 250° F (120° C) maximum will cause damage to transmission clutches, fluid, converter and seals.

• Drain and fill with the oil at 150 to 200 ° F (65 to 93° C).

Line up the Fill/Drain Plug with the upper access hole (A). Let hoist sit idle for 20 minutes for an accurate reading.

If oil level is not visible in sight glass, the hoist is underfilled. Oil escaping from vent plug (B) or is more than 0.13 in (3 mm) from the top of the sight glass is an indication the hoist is overfilled. If hoist is over filled drain the oil from the Fill/Drain Plug at the upper access hole. When replacing the oil, align the Fill/Drain Plug with the lower access hole (C) and drain the oil.

Failure to align the Fill/Drain Plug with the upper access hole prior to checking the oil level will result in an inaccurate reading.

Check fluid level every 10 hours or daily.

• Use sight gauge on side of tank, with boom down and all outrigger cylinders retracted.

• Drain and refill as necessary

NOTE: •

Environmental and other conditions can dramatically affect the condition of hydraulic oil and filters. Therefore, specific intervals for servicing/changing hydraulic oil, filters and hydraulic tank breathers cannot be set.

However, it is imperative for the continued satisfactory performance of Grove cranes that inspections be performed on the basis of how and where each crane is used. Air borne and ingested contaminants can significantly reduce the life of oil and the condition of hydraulic oil filters and tank breathers.

•

Under normal operating conditions, it is recommended that hydraulic oil, filters and breathers be inspected and oils sampled at least every 3 to 6 months and more frequently for severe operating conditions. The inspections should be for air borne and/or ingested particles and water that deteriorate and contaminate the oil (e.g., oil appears “milky” or no longer has a transparent clear to amber color). The return filter by-pass indicator should be observed daily to determine if the contaminants content may be high. If the indicator reaches the red zone or indicates a by-pass condition, the hydraulic oil must be sampled. The hydraulic tank breather should also be inspected to assure that it is not restricting air flow into and out of the reservoir.

•

To inspect hydraulic oil, fill a small glass container with a sample of reservoir oil and another glass container with fresh oil. Let the samples stand, undisturbed, for one to two hours and then compare the samples. If the reservoir oil is heavily contaminated with water the sample will appear "milky" with only a small layer of transparent oil on top. If the "milky” appearance was due to air foaming, it will dissipate and the oil should closely match the fresh oil. Should you have any questions, please contact your local authorized Manitowoc distibutor.

•

The hydraulic oil shall meet of exceed ISO #4406 class 17/14 cleanliness level.
